Ihis invention relates to manure spreaders. More particularly it belongs to that class or type of wagons used on farmsV in which fertilizer may be transported and dumped and spread 1 V charging the manure, and a beater or revolving breaker to separate the lumps ofthe substances being dumped. A

The object of this invention is the production of a wagon for handling manure of the type mentioned, the vehicle being equipped with parts of special formation and disposition illustrated in the accompanying drawings, and believed to be especially'efticient for the purpose intended.

Of the drawings, Fig. 1 represents a top view of all parts assembled. Fig. 2 is a side view. Fig. 3 a fragmentary top View of the front end of the body and frame provided with a cross bar or drag for connecting the wagon with a tractor. Fig. 4 is a front top View showing the steering devices for the iront wheels, and operating tongue or lever. Fig. 5 is aV side View slightlyenlarged, showing the lifting pinion on the front of the body, the vertical rack bar engaged therewith, and one of the gear operating levers at the front. The slant of the body, and the scraper are shown at the rear in this view. Fig. 6 represents one of the front wheels in vertical section with the angular stub, axle therefor, and the sprocket wheel and a portion of the sprocket chain thereon. Fig. 7 shows the rear or driving axle with the gear shift devices arranged towards one rear wheel, and the scraper clutch mechanism located towards the opposite rear wheel, together with the sprocket for driving the scraper mechanism. In this gure are also shown the gear wheels on the shifting and inclinable shaft, and also the pinion and rack bar engagement for raising Vthe front end of the body in the dumping operation. Fig. 8 shows the sprocket wheel which drives the scraper mechanism, andthe clutch devices therewith.

Throughout the drawings and description the same number is used to refer to the same part.

Considering the drawings, a body 1 of any chosen size or form is usually provided With an upwardly and rearwardly slanting back wall 2 to aid in discharging the manure when the body assumes the elevated position indicated by broken lines in Fig. 2. The body is supported upon rear l wheels 3 and 4 and front wheels 5 and 6. The

axle 7 for the rear wheels may be regarded as the driving axle. The front wheels are revoluble upony the stub axles 8 and 9 connectedv with a. vehicle framey comprising side bars asVV hereinafter referred to and transverse members 10, AtV the front, as best shown 4 there. is provided a tongue `or, lever ll'and thetongue may be hitched to suitabledraught animalsby means of the'customary cross trees, notv shown, on the kingY bolt 12. The king bolt carries a sprocket wheel 13, and as the bolt is turned by the tongue the sprocket wheel actuates the chain 14 driving the sprockets 15 and 16andA consequently the stub axles'8 and 9 and turning the front wheels for steeringV purposes. ,It Ais Vnot intended to limit this invention to the precise steering or draught means illustrated, and those elements maybe obviously varied.`

' At the front' end of the wagon, as `best illustrated in Figs. 2 and 5 are arranged the levers 17 and 18 in the positions indicated bythe reference numbers 17 and 18 in Fig. 4. Connected with those levers and extending parallelwith the side bars 22 and 23 of the'wagon frame and connected with crank arms such as the arm 2,1 shown in Fig. 5 with which the levers arev provided, are gear and clutch operating rods 24 and `25 as best shown in Fig. 7. Rod 24 throws the bell crank lever 26 pivotallyV carried by the cross member 21 of the frame, andrnoves the. link 28having' the bent end 29 in engagement, with the encircling groove 30 of the conical slide 31 on axle 7,' The slide may thus be-moved towards or away from rear wheel 6, and it impresses a longitudinal movement upon theshaft 32.v 'This shaft is capable of a movement lengthwise'and a rotativev movement, and it can assume an inclined position when the body is raised, `as indicated by the broken lines in Fig. 2. For the purposes'o'f this explanation the shaft is termed the inclinable shaft. As shown in Fig. 7 it will be noted' that when the cone slide, is withdrawn, a Acgil spring 33 onthe shaft 32 acts against a ,collar or the like onthe end of the shaftand Vreturns the shaft to its former position. Driven by axle 7 is a mitre gear`34 in mesh with a like 4gear 35 1GO which is provided with a key 36 sliding in a suitable key way extending lengthwise :in the shaft 32. Gear35 is carried against the bracket 37. As shaft zismoved longitudinally gears 38and 39 are 'brought alternately into engagement with 105 a pinion for mitre gear 40 on a transverse shaft 41 carrying the pinion 42 secured thereon and in engagement with the vertically disposed geared rack bar A43. 'Ihe rack bar has a universal end joint 44 with the transverse members 10 of the 11D frame as shown in Fig. 5. As the transverse shaft 41 is attached to the front end of the body by the bearing bracket 45, of which there is usually provided a fellow bracket 46 at the corner of the body as shown in Fig. 1, it is thought to be clear that the pinion will climb the rack bar and the front end of the body will be raised on the pivot 47 into the position indicated by the brokenvlines in Fig. 2, which is the dumping and spreading '.'position 'of the body. l

Again referring to Fig. .7, hen the lever 18 by its crank arm 21 moves the rod 25 lengthwise, and bell crank lever 49 which has the link .50

with the hook end 51 entering the encircling groove of the sliding collar 52 which isfmovable on the axle 7 towards and from Ythe wheel 5,.it,

correspondingly moves the clutch-disk. The slide V52 moves in engagementjwitha key 53 .carried I lengthwise by the axle 7 and the clutch disk may be moved thereby. The disk is marked 54` and itis providedl with any number and disposition of'r'oll'er pins 55 and 56 which as the disk 54`is rotatedjar'ecaused to enter the holes 57 and 58V the large sprocket 59 which is'loose on the axle 7. As best shown in Figs. 1, 2 and 5fthe sprocket 59 drives'the chain 60 and re- Volves the smaller sprocket 61 on the cross shaft 6 2 above Aand. at the'rear of the body. The shaft 62 lc a'rries'jthe sprocket wheels 64 spaced apart asshwn-,i'n Fig. 1, andthe shaft itself is supported iny bearing brackets '63, as shown in Fig. 2. Engaging `each sprocket 4wheel V64 is a chain 65 having Vprojecting scraping and manure separating` pins 66,V andV the chain passes around a sprocket'vwheel 67 'on a transverse shaft 68 illustinted in Fig. 5. 'It will be noted in Figs. 1 and Z'that" the body' 1 has aV baille or. partition plate 48 about` midway betweenthe position ofthe shaft-68 and thefront end of the body, and in Fig. 5 is shown a second baiile 69'extending in an'in'clined direction over the shaft 68 and having as set out in Fig.` 1 anumber of spaced slots orrecesses 70 through which pass the scraper `pins 66durin'g their movement with the chains thatA meshes fwitli'an idler intermediate spur gear 72 .and drives alike gear V73 on a'rear transverse shaft V 74. AShaft l74 is the beater shaft, and is provided with a ,plurality of projectingbeaters or vblades 75 arranged to act upon the'ma'terials justgas they are discharged ,from the slanting back wall 2 ofthe body'.

- Fig.`3 of the drawings represents'the Yfront end portion of the body having the same construction as described, but the side bars 22 and 23 are joinedin front by the cross beam or bar 76. This bar is providedwith oneor more orifices as illus-J trated and may be employed to connect the Wagon witha tractor lif so desired.'

The yoperationivof this invention" consists in drawing the wagon structure over the eldfor area upon which the manure Vis to vbe spread. If the' material'is in a nuidcondition theactuation by lever 17 of rod 24wi1l effect the engagement of either of the gears 38 or 39 withthe gear 40 on sliaftx41'. If the gear'38 be engaged with gear 40 as shown in Fig. 7 the lift gear 42 will climb the rack 43 and the front end of the body will rise. If gear 38 be engaged the body will be lowered to normal position. Should it be desired to draw the wagon about without operating the body hoisting members, the lever 17 is locked by means of the hand latch 19 and geared segment 26 in its intermediate position, and neither of the gears 38 or 39 will beengaged, the conical slide y3,1 holding both of those gears out of engagement. `When the material is in a mass and' must be distributed or broken up, the lever 18 and rod 25 are employed,

and the scraping mechanism and beating devices 'are' set in operation as will be readily understood.

The movement of the scraper pins or projections 66 inthe recesses 70 of the rear baie 69 keeps the baffle'clear and the contents of the body moving rearwardly. It wili be understood that this vlevers-or to the holding means therefor as shown,

those parts in various different shapesand 4relations being well known c ontrivances.
